ok i understand
but i think if u want to keep users play your game you should give them the filling that they are get on, reaching something
i think that a level should not take more then 5 minutes, after that or u lose or u won
but i play this game and i am still stuck in the same level, and after ten minutes its start getting boring
you should limit the time of the level from 3 - 5 minutes something like this, give the user a filling that they have to reach something i think if u rich the target point u should go to the next level not until the time is up or all jewels are transparent
u understand what i mean?
EDIT: oh i understand now the bricks behind the jewels should be transparent
then u go to the next level, maybe you should put a label how many bricks are left to complete the level
EDIT: one more thing is, ithink you should change the pictures in googgle play, the dark pictures u have 2 nice bright picture but all other are to dark, change them to show a good first look of the game before install it.
